Imaging apparatus and control method therefor

Abstract

An imaging apparatus is provided that includes a camera body on which a lens device is detachably mounted; a shake detection unit configured to be inside the camera body; and a control unit configured to determine an exposure time at a time of panning, wherein the control unit determines the exposure time at the time of panning based on a shake detection signal outputted by the shake detection unit.

What is claimed is: 
     
       1. An imaging apparatus comprising:
 a camera body on which a lens device is detachably mounted; 
 a shake detector configured to be inside the camera body; and 
 a processor, wherein the processor functions according to a program stored in a memory as a control unit configured to determine an exposure time at a time of panning, 
 wherein the control unit determines the exposure time at the time of panning using a shake detection signal output by the shake detector irrespective of whether the lens device mounted on the camera body corresponds to the panning. 
 
     
     
       2. The imaging apparatus according to  claim 1 , wherein the processor further functions according to a program stored in a memory as a setting unit configured to set a flow level of a background, and
 wherein the control unit determines the exposure time at the time of panning based on focal distance information, the flow level of the background set by the setting unit, and the shake detection signal. 
 
     
     
       3. The imaging apparatus according to  claim 1 , wherein the processor further functions according to a program stored in a memory as units comprising:
 a vector detection unit configured to detect a motion vector from a photographed image; 
 an extraction unit configured to extract an object vector from the motion vector; and 
 a calculation unit configured to calculate a correction amount used to correct an object shake based on the object vector. 
 
     
     
       4. A method of controlling an imaging apparatus including a camera body on which a lens device is detachably mounted, the method comprising:
 determining an exposure time at a time of panning using a shake detection signal output by a shake detector inside the camera body irrespective of whether the lens device mounted on the camera body corresponds to the panning. 
 
     
     
       5. An imaging apparatus comprising:
 a camera body on which a lens device is detachably mounted; 
 a shake detector configured to be inside the camera body; and 
 a processor, wherein the processor functions according to a program stored in a memory as a control unit configured to determine an exposure time at a time of panning, 
 wherein the control unit determines the exposure time at the time of panning based on a shake detection signal outputted by the shake detector, and 
 wherein, when the lens device mounted on the camera body corresponds to the panning, the control unit selects a shake detection signal to be used to determine the exposure time at the time of panning based on a comparison result of the shake detection signal output by the shake detector and a shake detection signal output by a second shake detector, which is a shake detector of the lens device. 
 
     
     
       6. The imaging apparatus according to  claim 5 , wherein the control unit determines the exposure time at the time of panning using the shake detection signal of which an output is stable among (a) the shake detection signal output by the shake detector and (b) the shake detection signal output by the second shake detector. 
     
     
       7. An imaging apparatus comprising:
 a camera body on which a lens device is detachably mounted; 
 a shake detector configured to be inside the camera body; and 
 a processor, wherein the processor functions according to a program stored in a memory as units comprising: 
 (1) a control unit configured to determine an exposure time at a time of panning, and 
 (2) a setting unit configured to set a flow level of a background, 
 wherein the control unit determines the exposure time at the time of panning based on focal distance information, the flow level of the background set by the setting unit, and the shake detection signal outputted by the shake detector. 
 
     
     
       8. A method of controlling an imaging apparatus including a camera body on which a lens device is detachably mounted, the method comprising:
 determining an exposure time at a time of panning based on a shake detection signal output by a shake detector inside the camera body; and 
 selecting a shake detection signal to be used to determine the exposure time at the time of panning based on a comparison result of the shake detection signal output by the shake detector and a shake detection signal output by a second shake detector, which is a shake detector of the lens device, when the lens device mounted on the camera body corresponds to the panning. 
 
     
     
       9. A method of controlling an imaging apparatus including a camera body on which a lens device is detachably mounted, the method comprising:
 setting a flow level of a background; and 
 determining an exposure time at a time of panning based on focal distance information, the set flow level of the background, and a shake detection signal output by a shake detector inside the camera body.
